Utilities schedules sanitary sewer work on Westside

       In an ongoing program to upgrade the sanitary sewer system, Colorado Springs Utilities will be working at or near the following Westside locations the week of July 19:
       · 18th and Colorado.
       · Highway 24 east of 22nd.
       · Highway 24 and 13th.
       · Cucharras between N. 30th and 27th.
       · Colorado between 32nd and 31st.
       · Pikes Peak and 35th.
       The program of rehabilitating old and damaged sanitary sewer pipes is called Sanitary Sewer Evaluation and Rehabilitation Program (SSERP). Once pipes are cleaned, inspected and prioritized, those pipes that are found to be deficient are “rehabilitated” through a modern form of pipe replacement that does not require digging an open trench, according to Utilities spokesperson Rachel Beck.
        One technology being used by Springs Utilities has been developed by Insituform Technologies, Inc. Insituform creates new pipes with a liquid- hardening technology within existing pipelines.
       As a result, the work must be performed all at one time - normally an 18-to-24-hour work period. Once the pipe hardens, the service laterals (pipes from residences and businesses that connect to the sewer line) are reopened with a cutter, aided by a television camera.
        Another trenchless technology being used in SSERP rehabilitation is called pipe bursting. In this process, a new polyethylene pipe is pulled into an existing sewer pipe through a manhole. The new pipe has a missile-like head, which when pulled through an old pipeline of equal or smaller size shatters the existing pipe, which is then pushed into the surrounding soil and used as fill.
